    But index coalesce does not reduce the height of the index.If the said indexes have 5-6 branches index rebuild would be a better idea.

    Rebuild or coalesced?

    Then, I found following information for one of the tablespace that has been growing very fast:

    select block_id, sum(bytes) from dba_free_space
    where tablespace_name like 'XYZ'
    group by block_id;

    block_id sum(bytes)
    562209 419430400

    and
    select total_bytes, bytes_coalesced, total_blocks, blocks_coalesced from dba_free_space_coalesced
    where tablespace_name like 'XYZ';

    total_bytes bytes_coalesced total_blocks blocks_coalesced
    419430400 419430400 51200 51200


    It seems to me system automatically coalesced the free space.

    The branch level is only up to 3 from dba_ind_subpartitions.

    The tablespaces are all locally managed and the initial=next, pctincrease=0. So it's not necessary to coalesce tablespaces.

    The table is a composite partitioned table (rang_hash). If I rebuild the index, I have to rebuild at subpartition level, alter index rebuild subpartition xyz ...

    Is there a command to coalesce index for this kind of table?

    Yes.

    What I really like to know is: is there any command down to subpartition level like alter index ... rebuild subpartition ....? Because this is a composite partitioned table.

    A 320 column table has 85 indexes and the table has 40 M rows and it's size 40 GB
